HEADLIGHT.

Application filed February 3, 1828. Serial No. 251,638.

This invention relates to improvements in headlights and moreparticularly to such as are adapted for use in conjunction withreflectors on automobiles and other vehicles,- the object of theinvention being to provide an electric lamp bulb which shall be adaptedto so direct the rays of light as to prevent glare and at the same timepermit a few of the rays to be projected forwardly through the end ofthe bulb and in axial alignment with the latter. a

With this andother' objects in view, the invention consists in certainnovel features as hereinafter set forth and pointed out in the claims.

. In the accompanying drawings,

Figure 1 is a view in elevation illustrating an embodiment of myinvention;

Figure 2 is a front end view, and

. Figure 3 is a view showing a slight modification.

An incandescent electric light bulb is illustrated at 1 and providedwith a suitable socket piece 2 to be fitted in a socket in a suitablereflector not shown. Y s V A shield for the bulb isformed by atranslucent coating on the bulb, which coating may be of white orcolored paint or similar material such as can be applied by a brush orby dipping, or frosted.

The applied shield com rises a portion 3 which covers ap roximate y onehalf of the body portion 0 the bulb and a portion 4 which covers the endof the bulb except at the center ofsaid end where the glass of the bulbis left transparent to form a comparativel small bull -eye 5 in axialalignment witl i the bulb and its connecting means to a reflector.

With my improvements the main portion of the rays of lig the form of theinvention t from the lamp will be so directed as to prevent glare but afew of the rays will be projected forwardl through the bullseye 5 sothat said rays will e parallel with the longitudinal axis of the lampand will afford l1ght;ahead of the vehicle suflicient for all practicalpurposes and at the same time avoid objectionable glare.

In the form of the invention shown in Figure 1, the edges of the ortion3 of the shield are at right angles to t e portion 4, while in showninFigure 3, the edges of the rtion 6 are at obtuse angles to the endportion 7, thus leaving a larger clear glass portion 8 than the clearglass portion 3 shown in Figure 1. Y

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is

1. An 'automobilelamp, candescent lamp bulb having a translucent shieldapplied t ereto, said shield comprising a portion extendinglongitudinally of the bulb and covering approximately one-half thereofand'a portion covering the end of the bulb except a portion of the bulbin axial alignment with the latter forming a bullseye.

2. An automobile lamp, comprising an incandescent lamp bulb having acoating of translucent material applied thereto, said coating comprisingtwo ortions, one portion extending longitudinal y of the bulb andleaving an oppositely dis sed clear glass portion, the other rtion ogaid shield covering the end of the ulb and leaving a clear glassbullse-in line with the longitudinal axis of the bulb.

In testimony whereof, I have signed this specification.
